An inverse, without any qualification, is taken to be the multiplicative inverse. is The inverse of a number, x (x not 0), is 1 divided by x. Any number multiplied by its inverse must be equal to 1. There is also an additive inverse. For any number y, the additive inverse is -y. And the sum of the two must always be 0.
The inverse if cosine 0.55 is 0.55
Always, unless the original number is zero. This does not have an inverse.
The answer will depend on what you mean by "opposite": the additive inverse or the multiplicative inverse.
Multiplying.

If the multiplicative inverse of a number is the number that you could multiply with the original number in order to obtain one, then the mulitplicative inverse of -15 and 2/3 is -3/47 negative three fourtysevenths, or negative three over fourtyseven.
The inverse function means the opposite calculation. The inverse function of "add 6" would be "subtract 6".
-6 is a number, not a function and so there is not an inverse function.
6
-6. The additive inverse of a number is the number, that, when added to the original number, causes it to equal zero. You can kind of think of it like an opposite number. So, the additive inverse of 2 is -2, and -4 is 4.
The additive inverse of 6 is -6, 6 + (-6) = 6 - 6 = 0.The multiplicative inverse of 6 is 1/6, 6 x 1/6 = (6 x 1)/6 = 6/6 = 1
The additive inverse of 6+4i is -6-4i since their sum is 0. It is analogous to real numbers where the additive inverse of 6 is -6 since 6+-6 =6-6=0 In the case of complex numbers, we add them by adding the real parts and then adding the imaginary parts. So to find the complex additive inverse of a+bi, we find the inverse of a which is -a and of bi which is -bi and so the additive inverse is -a-bi
An additive inverse is whatever will combine to make zero, in this case, -6.
25/6 = 17/6 so the multiplicative inverse is 6/17.
